It is indeed coming, but no one knows when. Not even, Amazon *shock* Turns out they have been putting imaginary release dates on their website for quite a while, and when that date comes and goes, they just stick a new, later release date on
So, yeah, ignore Amazon..
Anyway, UT3 plays pretty well on my 2.4ghz ATI2600 20" iMac via Bootcamp/windows XP. I doubt the Mac port will be as fluid however, going on past experience from just about every other Mac game out there, so im not sure the Mac version would run so well on my iMac (But i'll try the demo, if and when we get it)
Theres mutterings on the Epic games forum of a new, expanded version of UT, so I wonder if the Mac version is being held back for that.
Great game though it is, glitches and poor customer relations from Epic pretty much doomed UT3 to failure.. Not many online players
Im hoping one way or another however, that things pick up!
